What methods can I use to treat head lice?

Most importantly, ensure that a correct diagnosis/identification has been made before considering any treatment options. An old infestation, manifested solely by hatched eggs, is not a cause for treatment. Treatment should be considered only when active (crawling) lice or viable eggs are observed (refer to the images of lice and eggs). Several options exist to eliminate an infestation, but some methods are better tested than others. Success will likely depend on an integrated approach that relies on several of the methods listed below, combined with perseverance and a bit of levity. Because the egg is particularly resistant to some chemical treatments, a second treatment is often required about 10 days later to target the nymphs that hatched after the initial treatment.
